I haven’t distro hopped much in the past few years, so I am near clueless. I know that Linux Mint has a graphical updater and I vaguely remember openSUSE having it, though I’m not so sure on that one, because as I mentioned, it’s been a while. Especially curious if any Arch-based distros have it.
It’s not recommended, but you can use any graphical updater you want, by installing
packagekit-qt6. The reason it’s not recommended, however, is that if something goes wrong, you’ll have a harder time figuring it out without pacman’s logs; also, it won’t merge .pacnew files, increasing the chance that something goes wrong after a reboot. If you just wanna use a graphical updater for flatpak stuff, that’d be fine, but you’d still need to usepacman -Syuto update system packages.
